Philip's story

I have a great interest in data base management and as a data base administrator having a data base security is vital. It is important to develop a security policy for every database. The security policy establishes methods for protecting your database from accidental or malicious destruction of data or damage to the database infrastructure.
Each database can have an administrator, referred to as the security administrator, who is responsible for implementing and maintaining the database security policy If the database system is small, the database administrator can have the responsibilities of the security administrator. However, if the database system is large, a designated person or group of people may have sole responsibility as security administrator. So I wish to learn more on how to protect my data base and hence need the knowledge of oracle.
